The monster slaying vespari, Corrigan Lockhart, is gone, having faced his final battle, but his legacy is secured in his apprentice, Wynonna Lockhart. In his absence, Wynonna must now carry out her master’s final wishes for her by leaving the harsh desert and everything she has ever known behind to travel to the bustling coastal city of Alexandria. There she must meet with the elders of the Vespari Brotherhood and attempt to receive their confirmation into the monster slaying ranks of the vespari. What she Wynonna find, however, is an inhospitable environment where malevolent schemes threaten to both stand in her way as well as tear down the vespari order itself.
